Is the reason why some properties on CASH or POINTS never show any availability on Wyndhams website? Ive been trying to see if I can get a room at the Kona Wyndham Club or Club Wyndham Royal Sea Cliff. But when I check every single day shows no availability on points or cash. The preferred dates that Im looking at are March 17th- 20th. But when I call customer service, I get nowhere and transferred like 5 times before I give up.

Any advice would be great. Or what to say to be able to get some reservation.
